If you let people create keyspaces with a mouse click you will soon run out of

I use Cassandra to provide a self service "storage service" at my organisation.

In our app, we would like to offer cassandra 'as-is' to tenants. It that
case, each tenant should be able to create Keyspaces as needed. Based on the
authorization, I expect to implement it. In my view, the implementation
options are as follows.
1) The name of a keyspace would be 'the ac
Hi Stu,
I highly appreciate your help.
First, I would like to get familiar with the Cassandra, especially the
current work on mult-tenancy and security. Is there any resource other than
the wiki that can be used to learn about the internals of the Cassandra. I
would appreciate your suggestions o

There are some very straightforward solutions to this particular problem: I
wouldn't rule out running with a very large number of

Hi Brandon,
I would like you feedback on my two ideas for implementing mufti tenancy
with the existing implementation. Would those be possible to implement?
